Fly Geyser, Gerlach, Nevada



After knowing of the existence of this geothermal feature in northern Nevada for a number of years, from photos in photo magazines, we finally got to go on a tour of this private ranch to see the Fly Geyser up close and personal.  This feature resulted from a geothermal test well drilled in 1964 that was either never capped or was capped improperly and has been spouting hot water into the air ever since.

The cone has formed from deposition from the mineral-rich water cooling as it emerged and is growing at a rate of 6 to 8 inches per year.  This is a phenomenal rate for a geyser.  But, then again, this is not a true geyser.  A true geyser has a quiet phase and an eruption phase.  We've checked the terms for geothermal features and it looks like perpetual spouter would be the most accurate term for it.  In any case, this mound of mineral deposits and brightly-colored algae growing on this cone is a spectacular sight.

These photos were taken with an eclipse filter on the lens to force a long shutter speed of 30 seconds and f16 and it produces a silky look for the five spouts of water emerging from the top of the cone.

Remember, it's not just a picture, it's a story.

Eye of the Needle, Death Valley National Park, California


This is a nighttime shot of a natural window in Death Valley National Park, California, called Eye of the Needle.  Seems self-explanatory how it got its name.  This arch is about one and a half miles up Echo Canyon on a dirt road.  The road appears to head straight toward this arch, but then wraps around the rock formation, so that you can see this arch from both sides while driving.

We camped near this feature and were taking starlight shots of it when someone drove by lighting up the rock formation with their headlights. This photo was taken with a zoom lens set at 28 mm and the exposure was 30 seconds at f/3.5 with the ISO set at 800.

Remember, it's not just a picture, it's a story.

Half Dome with a cloudy scarf



Got this image on a winter trip last February to Yosemite Valley. The clouds formed small puffs of cotton around Half Dome and slowly drifted around it. This cloud moved into just the right spot as the sun was getting lower in the sky, that its shadow went all the way across the face of Half Dome. Another nice feature was the snow on top of Half Dome and on the ridge west of Half Dome, too.

The ISO was set for 100, shutter speed at 1/250 sec, and the f/stop was 5.6. This was taken right about 5 PM so it was getting close to sunset for the third week in February. Taken from the Sentinel Bridge in Yosemite Valley.

Remember, it's not just a picture, it's a story!
